Title: Spatial localization of dispersed single walled carbon nanotubes into useful structures
Inventor: CLARKE MARK S F
IPC: B82B3/00
Filed: 2002-06-19
Granted: 2009-04-28
Abstract: Methods of aligning single walled carbon nanotube structures into selected orientations for a variety of different applications are achieved by initially dispersing the nanotube structures in aqueous solutions utilizing a suitable dispersal agent. The dispersal agent coats each individual nanotube strzcture in solution. The dispersal agent may be substituted with a suitable functional group that reacts with a corresponding binding site. Dispersed nanotube structures coated with substituted dispersal agents are exposed to a selected array of binding sites such that the nanotubes align with trhe binding sites due to the binding of the substituted functional groups with such binding sites. Alternatively, crystalline nanotube material is formed upon deposition of dispersed nanotube structures within solutions into channels disposed on the surface of the substrate. Combining dispersal agent chemical modification techniques with deposition of the nanotubes into substrate channels is also utilized to produce useful structures.

Abstract: A method and system for compensating for side effects of cross gain modulation in amplified optical networks, which allows reliable identification of expected and unexpected channels in the network is provided. Each optical channel traveling in the optical network is marked with a unique channel signature (expected channel signature), having one or more dither tone modulated onto the optical channel; followed by detecting a spectrum of tones, including said modulated dither tones and ghost tones thereof produced by the cross gain modulation in the optical network, at various locations in the optical network. Amplitudes of the spectrum tones, which belong to the expected channel signature, are compared with a first threshold, while amplitudes of the remaining spectrum tones, which are not the valid tones, are compared with a second threshold, which is lower than the first threshold. The spectrum tones are identified as valid tones if their amplitudes are above the first threshold; and an alarm signaling that the expected channel signature is missing is generated if the amplitude of the spectrum tone is below the first threshold. Yet another alarm is generated signaling that an unexpected channel is detected in the network if the amplitude of at least one of the remaining spectrum tones is exceeding the second threshold. Alternatively, the other alarm is generated if amplitudes of the remaining spectrum tones belonging to one of the allowable channel signatures in the network are above the second threshold. A corresponding system incorporating the step of the methods described above is also provided. 25

Abstract: A drive mechanism for a power tool is disclosed, in which the power tool has a housing, a motor provided in the housing, and an output shaft adapted to be caused by the motor to execute reciprocating motion. The drive mechanism comprises a gear plate (34) adapted to rotate about a first axis (Z-Z) and having a plurality of elongate first teeth (33) extending substantially in a plane perpendicular to said first axis; and connecting means cooperating with said gear plate (34) and adapted to cause reciprocating movement of an output shaft of the tool in response to rotation of said gear plate about said first axis, wherein said reciprocating movement has a component perpendicular to said first axis. Conventional drive mechanisms which have an output shaft adapted to be caused by the motor to execute reciprocating motion generally have bevel gears with teeth formed at 45° to the axis of rotation of the gears. By providing a gear plate and connecting means which provide a reciprocating drive force for an output shaft of a power toot with teeth formed at 90° to the axis of rotation of the gear, instead of teeth formed at 45° to the axis of rotation of the gear, this provides the advantage that the gear is cheaper and easier to make as the gear teeth do not have to be formed as accurately as prior art inclined gear teeth. Also, the gear plate does not need to be as accurately located relative to the gear driving it, since some longitudinal movement in the direction of the mutually engaging teeth is possible without the gears ceasing to function correctly.
